Question

Compare and contrast the properties, structures, and reactivity of SO3 and CrO3

Answer 1

Physical state at room T

SO3 --> most likely gas state

CrO3 --> most likely a solid

Reactivity:

Type of bond

SO3 --> covalent bonding ( nonmetal + nonmetal)

expect low melting points/boiling point

CrO3 --> ionic bonding ( metal + nonmetal)

expect high melting points/boiling point

CrO3 --> slightly soluble in water

SO3 --> almost not soluble in water

reactivity --> CrO3 --> oxidant material

SO3 --> tends to form H2SO4 acid in solution
